Abstract
The invention discloses a gas inlet pipe bolt for an engine. The gas inlet pipe bolt for the engine is characterized in that a hexagonal screw head is arranged at the upper end of a screw rod; a pressing cap is arranged at the periphery of the connection position of the hexagonal screw head and the screw rod; a ring of locking teeth are distributed on the end face of the bottom of the pressing cap; and a lead screw part is arranged at the lower part of the screw rod. According to the arrangement, the gas inlet pipe bolt for the engine is made of special steel, and corrosion resistance and locking performance of the bolt are guaranteed due to the locking teeth and special surface treatment.
Description
Technical field
The present invention relates to a kind of standard piece, is a kind of engine intake pipe bolt specifically.
Background technique
Engine intake pipe bolt is the fastening piece high-strength bolt that is used for engine air inlet tube, suction tude belongs to the elongate rod bolt, the engine charge tube vibration easily makes suction tude bolt looseness or fracture, the suction tude bolt that exposes is perishable, above conditional request suction tude bolt must the intensity height, impact toughness is good, corrosion-resistant, anti-loosening property is good, a part of before bolt adopts external import, is difficult to guarantee above performance.
Summary of the invention
Purpose of the present invention is that a kind of intensity height, impact toughness, corrosion-resistant, engine intake pipe bolt that anti-loosening property is good are provided.
To achieve these goals, the present invention is provided with hexagonal spiral shell head in the upper end of screw rod, and periphery is provided with pressure cap in the joint of hexagonal spiral shell head and screw rod, is laid with all locking teeth on the bottom end face of pressure cap, and screw mandrel portion is located at the bottom of screw rod.
By above setting, the present invention adopts the special steel manufacturing, adopts cold-heading molding, helps guaranteeing material inside organization.The carbon potential parameter is adjusted in the heat treatment of atmosphere protection multipurpose stove, has guaranteed the product mechanical property.The decay resistance and the anti-loosening property of bolt guaranteed in locking tooth of the present invention and special surface treatment.
Description of drawings
Now the invention will be further described in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the worm's eye view of Fig. 1.
Among the figure: 1, screw rod, 2, hexagonal spiral shell head, 3, pressure cap, 4, locking tooth, 5, screw mandrel portion.
Embodiment
As shown in Figure 1, 2, 3, the present invention is provided with hexagonal spiral shell head 2 in the upper end of screw rod 1, is provided with pressure cap 3 in the joint periphery of hexagonal spiral shell head 2 and screw rod 1, is laid with all locking teeth 4 on the bottom end face of pressure cap 3, and screw mandrel portion 5 is located at the bottom of screw rod 1.By above setting, the present invention works under yield situation, unique texture and inherent technical order provide guarantee for the performance of whole motor, the special shape of locking tooth 4 is adapted to the specific (special) requirements of suction tude, be unlikely to loosening under the effect of alternating force, performance and anti-loosening properties such as corrosion-resistant are guaranteed in special surface treatment.Reasonable by this suction tude bolt geometry design of installation checking, integrated performance index is good.
